Hey guys, just curious as to how many are running a C rated tire.

Today I bought a new set of tires for my truck. Its an 05' 2500 crew cab diesel. I called the local Pep Boys, asked if they had any BFG TKO's in a 265/70/17 load rang E. They said, they did. I went down dropped the truck off....come back this afternoon...and they've mounted a C rated tire. I told the guys, this isn't what we discussed. Of course he says "whoops" sorry about that, but its not a big deal unless you tow a lot. Now, I don't tow a lot, but when I do its a 10K backhoe or a 8K tractor. The tires are rated at 2470lbs load per each...so they support the weight of the truck just fine and actually ride really nice. His advice was to try them and if I didn't like them the store has a 30 day return policy...just bring them back.

So what's everybody's opinion about running a C rated tire? Any safety issues? Or when towing, will it just be a little mushy...potentially squirrely?

 

I did that on my 97 2500 CTD once to see if the ride was better. The ride was better but new tires always ride better anyway and I went back to E's the next time. C's were high enough weight rating for what I tow but they might not be for you. Craig

 

I tired D rated tires, all came apart by the 30,000 mile mark.

E rated tires since, no problems.

 

I just swapped my factory tires(BFG Rugged Trail) out at 101k. I was hoping to get similar mileage out of these. I wondering if I can do that with a C rated tire? I'm using them on the upper end of their load/rating scale...on the other hand they are still with in spec of their weight limits?

 

I wouldn't feel comfortable with C rated tires on this truck.

If I were you I'd have the truck back at the shop so they could put an E rated tire on there. You probably got charged for an E too.

 

I would take them back, our trucks are rated with e rated tires empty,

 

When I bought my truck it has D rated kumo 315-70-17's on it. I just replace them with D rated yokohama geolanders in the same size, the truck rides much better. I don';t think I would be comfortable with C rated tires on this truck.

 

I would absolutely NOT run a C rated tired on these trucks! They recommend a E rated tire for a reason. The guys were being lazy at Pep Boys

I wonder what the lawsuit would be against them if you can get it in writing that a C tire is fine and then you have a blowout on the freeway!

 

I wouldn't do it. Like the others have said, the truck came from the factory with E range tires and they were there for a reason. You mentioned that when you tow, you yow heavy. According to your sig you're running a 2500. Throw 1000-1500 pounds of tongue weight on the truck, maybe more and you're on borrowed time, not to mention the heat in your location. Take'em back while you still can.

 

yeah...I'll be talking to Pep Boys tomorrow. There is a pretty good bit of tongue weight when I tow. So, this isn't going to work.

 

That is what I was picturing, a front tire blow out at highway speed won't be pretty under a 4k lb front.

I've dealt with Pep Boys a few times with other people's cars and never like it. They never seem to have "a full set of four" of the same tires on their shelves. Discount Tire has gotten my money.

 

especially with a backhoe in tow

 

...

 

One other thing to remember, your valve stems. Most of these places forget that valve stems have pressure ratings just like the tires do. DO NOT drive away with a full rubber valve stem in place. The correct one is brass and rubber, with the brass piece being about 1/2 inch long. The next, and best option, is a bolt in stem.

 

Les Schwab tried to do that to me on my toy hauler.

Take it back and get the right tires on there! Show them the sticker on the door, that should make 'em feel foolish.
